Geographical coverage corresponds to the Meteosat satellite field of view, i.e. covers Europe, Africa, Atlantic Ocean, Middle East. Spatial resolution is 3 km at Nadir, and approx. 4-5 km at 45° of latitude. Data are available with a time step ranging from 15 min to 1 month. The time coverage is from Feb. 2004 up to current day-2 for HC3v5, and up to day-1 for HC3v4.

HelioClim-3 Real Time and Forecasts

Provides 15 min and hourly HelioClim-3 (version 4) time series for the current day and for d+1.

Current day: the service is updated in real time from sunrise with the latest upcoming Meteosat image, to provide HelioClim-3v4 time series. It is completed until the end of the current day with a persistence model.Next day: the Similarity Forecast model performs a statistical investigation of the HelioClim-3v4 database to find the most similar day in the database to provide an estimation of the radiation for the coming day.

NB: HelioClim-3v5 can not be available in real time and forecast since the data are only available at d-2.

Extraterrestrial Irradiance and Top of Atmosphere

Daily values of Extraterrestrial Irradiance (E0), i.e. received by a plane normal to sun rays and outside the atmosphere, and Top of Atmosphere (ToA) radiation, i.e. received by a horizontal surface and outside the atmosphere. E0, in W/m², depends on the sun-earth distance, and thus on the date. ToA is given in irradiance (W/m²) and irradiation (J/m², Wh/m²).

Guidelines for UV exposure

Daily values of UV exposure computed from HelioClim-1 solar radiation database, which implements the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines on protection against UV radiation regarding exposure of the skin.

Altitude

This Web service, provided by MINES ParisTech, returns the altitude value in meters from the Shuttle Radar Topography Mission (SRTM) of NASA (USA), from GTOPO30" and from TerrainBase5'.

SRTM in a tile

This service provides tiles of surface elevation from the Shuttle Radar Topography Mission (SRTM) of NASA (USA). Please note that it is listed in the catalog www.webservice-energy.org. Click on "more informations" to visit the website of the catalog.

Astronomy

Solar Geometry 2

Solar Geometry 2 is the second generation of library for computing the relative position of the sun and the earth made by the MINES ParisTech. Valid over the time period 1980-2030, the algorithm is 20 times faster than the well-know SPA algorithm (Solar Position Algorithm), with an accuracy order of approx. 0.005°. The code is available both in C langage and in Matlab. More information on the MINES ParisTech OIE research lab website.

APOLLO Cloud Statistics

This Web service, granted by ESA and provided by both DLR and TRANSVALOR, provides reports in pdf format with the APOLLO cloud physical parameters statistics on a limited number of sites, as a further help in the characterization of a solar site.

The August 2015 description of the product and statistics has been improved and enriched with examples and feedback from our user's trials. It describes also the two products which are available "on demand" from Transvalor.
